Shopify Integration with Spring Boot App

I’m looking for a developer to integrate Shopify API into my existing web application.
Users should be able to connect their Shopify store via OAuth, and the system should fetch orders from their Shopify account into the app.

The app is already fully functional — this task is only about adding the Shopify integration.
I know exactly how it should be done and can provide full guidance, API keys, and test data.
I just don’t have time to implement it myself.

⸻

Requirements:
1. Implement Shopify OAuth login (connect account).
2. Fetch orders from the user’s Shopify store via the Shopify Orders API.
3. (Optional but nice to have) Implement Shopify webhooks for automatic order syncing.

⸻

Tech Stack:
• Backend: Spring Boot (Java 21)
• Frontend: Angular 20 (SSR)
• Database: MySQL
• Communication: REST (JSON)

⸻

What I Provide:
• Full explanation of the existing structure
• Test keys and example requests
• Guidance and assistance throughout development

⸻

Expectations:
• Proven experience with Shopify API (OAuth & Orders)
• Knowledge of Spring Boot and Angular
• Clear communication and fast delivery (this is a small, well-defined task)

⸻

Note: This is not a full build — it’s a simple integration that should take only a few hours for an experienced developer.
